IMPROVEMENT. iN VAPOR-LAMPS.

't Specilicaiion forming part of Letters Patent No. 46.266', dated February 7, 1865.

-Ta all whom it may concern:

Beit known that I, .J. J. RIDDLE, O't-Oincinnati, in the county of Hamilton and State ot' Ohio, have'invented a new and Improved Vapor-Lamp.; and I do here-by declare that the following-gis a full, clear, and exact descriptin of the same, reference being'had to4 the accompanying drawings, making lpart of this specification, iu whichs Figure'l is 'a longitudinal vertical central section of my invention, withneedle working from' the top. Fig. 2 is a horizontal section of the same. Fig. 3 isa detached longitudinal central section of my burner.and' oiltube, with the needle arranged from below the bottoni of the lamp. Fig. 4 is a transverse verti# lcal section of the burner, as shown in Fig. 3.

Similar letters of reference indicate-corresponding parts.

The object of this invention 1s a vapor-'lamp duced through theiiller F, and the air in the air-space is compressed by means of Aan airpump, P, which is introduced through the top a ot the reservoir A, and extends down near to .its bottom. The air pressing upon the sur-j .face of the burningliquid forces thevsame up vthe oil-tube O' to the Vvalve-seat d, which is provided with a very small holethrough which .the liquid canpass when the needle 'n is moved 'out of its valve-seat.l Said needle may either be made to pass down through fthe burner from above, as shown in Fig. 1', and in that ,case it is provided .with a screw-thread and 4operated by a milled head or by'a'handle iu- 'serted in or attached to said head; or said needle may be made to pass up through the bottom-of the reservoir A, and in that case it is operated by a screw or other suitable device from below, Aas shown in Fig. 3.

The oil-tube O is' solderedin the abutment h, which is firmly secured by solder yorother means in the neck of the reservoir A, and whenouce properly secured said tube is never disturbed, and lit is not liable to work loose.

The pump is easily screwed into the lamp airtight Aand as easily kept so, there being no strain or jarring motionv to loosen the same. The filler F is as easily kept air-tight by lead vor cork packing put into the cap to keep them from spreading. All jointswith a sliding motion through them are avoided iu this lamp,

'spontaneous y, or by the action of a spring, as

soon as this excess of pressure ceases. This tiri case is fastened to the pump-barrel by means .of a screw-thread, e', and it draws out 'with said barrel, so that the valve s can be readily repaired when'V needed. This valve may, however, be made of a simple ring of thin and elastic india-rubber,'which will easily open and close, and which is not liable to wear out, or which, when it should wear or' become deranged, can be4 readily replaced. A screw-thread, d', serves to .fasten the barrel in the socket f', yand holes d admit airinto the pump-barrel whenever the plunger is raised above the same. A cap, c, forms the guide forthe pump-,rod fw. On forcing the plunger down, the air contained in the lower part of the barrel is forcedl out through the valve y', and it passes into 'case t, and from it through. the valve s into the lamp. The'valve y! consists oiva dat disk, the surface of which is covered with india-rubber or other suitable material, and which is held up by a spiral spring, y. l v

The requisite quantityof air to support combustionis admitted to thc neck ot` the reservoir A above the abutment h, through the aperture e, 'which is closed by a screwplug or in any other suitable manner. The burner is heated by alcohol or other suitable material, which is burned in the cup g g' and a spiral, s, ot' loosely-coiled copper, withA or without twisted copper inits center, serves to turn the oil into gas before lreaching valveseat d. This spiral is 'suspended from a slight shoulder uder the valvefseat, so that it is held open by its ownpweight. A,

`My improvedburner is' represented in Fig. 3, 1t is slipped or screwed overlthe tube t n, which contains the vulve-seat d, andfas'tened bythe pin "r.` The.tul'nllar` socket fp ot'the burner is either corrugated or 'il uted in a. longitudinal direction, (see Fig. 4,) so aste letsuffcent air pass up froni .the neckft f of the reservoir to support combustion. rI his air mixesf `with the gas or vapor passiugwup through` the oil-tube O' and valve-seat d, and

' the gas-'mixture passes overtime plate A and down through openings c. land circular ehannel c* to the openings b, when' it is ignited. The channel c* is filled with'coiled copper, o,

and in passing through said channel, ,which constitutes Vthe hottest portonof the burner,

the gas is highly heated, so that it will readily burn. A cupQshaped flan ge, g', serves to throw the flame' upward. The hentot'l the copper coil o' is communicatedthrough the iluted shanltp-to' the tube fv,.so as to keep the latter h ot enough to burn'u'p'all soot ,which accumulates therein, and alsoto' perfectly turn the oil into gais and v whitenthe dame; and I must' two parts, which are vseparatedv from each' other by the horzontnlpaittion git. A pipe, qw hichv is 'solderedtov the side of thesocket, conducts `the oil from the reservoir A to the upper part of the socket R', and throughl it to the oiltube O. The lower part ofisaid socket forms astnfting-box to make an ,air and oil tightjoint around theneedle n, anda screw, 11.*, which .is tapped into an` arched bracket attached to the lower end ofther socket R',

serves to'raise and lower said needle.` A nut,

W, screwed from' below into .thes'ocket It', servesto tighten up the packing, so that the joint in the stuing-boX-'can `'always be held tight andin good order without disturbing any other part of the lamp.
